How does being made of many cells help large organisms maintain homeostasis?

Being made up of many cells helps large organisms maintain homeostasis as follows:

Cells act in a coordinated way in the organisms and they prevent changes in the environment from interfering with their functioning.

The existence of large complex organisms was only possible thanks to the evolution of an internal environment, whose physical and chemical conditions must be maintained at relatively constant levels, favorable for cells.

The cells were able to specialize in tasks that would help maintain specific aspects of the internal environment.

For example, some cells organized into tissues specialized in maintaining the balance of salt and water; others, in providing nutrients; while others, in maintaining appropriate levels of oxygen and carbon dioxide.

In addition, specialized tissues and organs form systems within the internal environment of the organisms.

For example, the digestive system that provides nutrients; while the cells related to the circulation, among other things, distribute oxygen and nutrients.

In this way, specialized cells and tissues must continuously correct the physical and chemical composition of the internal environment, so that it remains conducive to life.

The maintenance of relatively constant conditions in the internal environment is what is called homeostasis.

Therefore, we can conclude that being composed of many cells helps large organisms to conserve specific aspects of the internal environment to maintain its homeostasis.

Explanation:

To maintain homeostasis, unicellular organisms grow, respond to the environment, transform energy, and reproduce. The cells of multicellular organisms become specialized for particular tasks and communicate with one another to maintain homeostasis. All body systems work together to maintain homeostasis.
